Learn CSS Box Model Lesson- Seems like there is bug

I had the same issue in another section where I had the correct answer and when I ran the code it showed my answer as incorrect. I decided to view the answer and the first part was the answer that I had. Did anyone else have this problem?

Have you tried laying it out how they like it?

It’s not the only way to write CSS, but I think it’s the most readable, so CC wants you to do it this way as opposed to a less readable format.

Yeah I tried it multiple ways even the way you shared and it didn’t work. I just took a screenshot of one of the final ways that I tried. Thanks for replying to my message.

Could you post a link to the lesson, please?
